OMI Total Column NO 2 – Monthly Average July 20-Aug. 20, 2014

OMI, Pandora Coincidence – :45:14 Analysis Steps 1.Calculate temporal average of satellite overpass ±250 km from center of study region 2.Calculate temporal average of quality-controlled Pandora data ±30 min from satellite overpass 3.Calculate spatial average of coincident Pandora data 4.Calculate spatial average of satellite data ±50 km of Pandora data

DANCE – Pandora O 3 Column; July 30-Aug

OMI O 3 Column versus Pandora O 3 Column y = 1.11x – 21.78

OMI NO 2 Column versus Pandora NO 2 Column y = 0.25x
